Title: Solenoid valve
Inventor: TACKETT WENDELL D
IPC: B60T8/36
Filed: 1990-05-09
Abstract: ABSTRACT OF THE DISCLOSURE A  solenoid  valve  (10)  comprises  a  body  (12) received within a stepped opening (13) of a modulator body (11).  The solenoid valve (10)  includes a first opening (16)  communicating with a chamber  (40)  and second  (20) and third (22)  openings communicating with an  interior area (30) of the solenoid body (12).  Located within the chamber (40) is a shuttle valve (50) having a longitudinal through-opening  (52) with an orifice opening (54) and a transverse opening  (56)  communicating with  the chamber (40)  and  intersecting  the  longitudinal  through-opening (52).  An armature (100) is disposed within the interior area  (30)  and has  a first valve member (101) which may seat sealingly with a valve seat (53) of the longitudinal through-opening  (52)  of  the  shuttle valve  (54),  and a second valve member (102) which may seat sealingly with a valve seat (28) of the third opening (22).  The armature (100) has a pair of parallel axial through-passages (105). The armature (100) and shuttle valve (50) are biased by a spring (51) and each move reciprocally within the solenoid body (12).  The second opening (20) extends transversely through  the  solenoid  valve  body  (12)  and  intersects orthogonally  a  pair  of openings  (21) which communicate with the interior  area  (30)  and  are  coaxially aligned with  the  pair  of  axial  through-passages  (105)  in the armature (100).  A coil (90) is disposed about the shuttle valve (50) and armature (100).  Energization of the coil (90) causes the armature (100) to move and seat the first valve member  (101)  within  the valve  seat  (53)  of  the longitudinal through-opening (52) and separate the second valve  member  (102)  from  the  third  opening  (22),  thus permitting fluid to flow from the second opening (20) to the third opening (22).  A pressure differential created across the shuttle valve (50)  and armature  (100)  causes conjoint movement of the shuttle valve (50) and armature 5100) toward the third opening  (22)  so that fluid flow from the chamber (40) directly to the transverse opening (56) is substantially restricted and fluid in the chamber (40) flows through the orifice opening (54).

Inventor: COHEN TODD J
IPC: A61N1/18
Filed: 1990-07-26
Abstract: A system for and method of treating a malfunctioning heart is based on hemodynamics, the pressure at a site in a patient's circulatory system being sensed. A signal is developed representative of mean pulmonary artery pressure (MPAP), mean pulmonary vein pressure (MPVP), mean pulmonary capillary wedge pressure (MPCWP), right ventricular systolic pressure (RVSP), right ventricular end diastolic pressure (RVEDP), or right ventricular pulse pressure (RVPP). A signal representative of fixed or varying baseline pressure is provided and if the short term current pressure differs therefrom by a predetermined value, an indication of hemodynamic compromise, cardioversion /-defibrillation is effected. In a second embodiment, the determination of whether the difference between fixed or varying baseline pressure and current pressure is undertaken after a rate criteria (for example a heart rate above 155 b.p.m.) has been met. In a third embodiment, the rate and pressure criteria both must exist at the same time, before cardioverting/-defibrillation is initiated. In a fourth embodiment, a microprocessor is used. The system may be integrated with antitachycardia and/or antibradycardia pacemakers.

Title: Restraining protective seat for infants
Inventor: MINAMI YOSHIHIKO
IPC: B60N2/28
Filed: 1990-06-28
Abstract: ABSTRACT    A reclining adjustment mechanism (20) for continuously varying the reclining attitude of a seat main unit (2) of an infant: restraining protective seat (1) is provided, and a protecting member (10), which does not allow a vehicle seat belt (7) to come into direct contact with the seat main unit (2) when the seat belt (7) is tightened, is interposed between the seat belt (7) and the seat main unit (2).  Further, an engaging mechanism (2c, 10d, 11, 12), which causes the protecting member (10) and the seat main unit (2) to engage when the vehicle undergoes deceleration in excess of a predetermined value, is provided.  Accordingly, the reclining attitude of the seat main unit can be adjusted continuously by the reclining adjusting mechanism.          As a result, the seat belt does not directly engage the seat main unit (2) owing to the protecting member when an infant restraining protective seat is secured to the vehicle seat by the seat belt.  Accordingly, the reclining attitude of the seat main unit can be adjusted continuously with the seat belt left in the tightened state.  Since the protecting member and the seat main unit are engaged by the engaging mechanism when the vehicle undergoes a large amount of deceleration, a change in reclined attitude owing to movement of the seat main unit is reliably prevented.
